I followed your steps to shut down NetworkManager and then start wicked. Still no IP address with my wireless card with wicked. 'ifconfig' shows wlp5s5 is up but no connection. My /etc/sysconfig/network/ifcfg-wlp5s5 file has similar entries as the example, but I have no line like this: #WIRELESS_WPA_DRIVER='nl80211,wext'
